DailyWireless got a note from John Stover, President of Gilland Electronics, who said our recent article on millimeter band radios missed one — their ELVA-1 radio (pdf) which delivers 1.25Gbps Ethernet in the 71-76/81-86GHz frequency band.
Gilland Electronics, of Morgan Hill CA, markets the ElvaLink PPC-1000 which recently received FCC Equipment Authorization (pdf). It’s made by ELVA-1 Ltd., of St. Petersburg, Russia. The authorization enables these 1.25Gbps, full-duplex wireless Ethernet links, operating in the 71-76GHz and 81-86GHz bands, to be made available to the United States market.
According to Stover, “ELVA-1 is a well-established and respected partner, with a long history of profitability and millimeter wave engineering expertise.”
The PPC-1000-E link provides a 1,250 megabit-per-second (Mbps) wireless Ethernet data pipeline. The result is terrestrial fiber equivalent performance, reliability and security, but without the high deployment costs associated with outdoor fiber installation.
Using PPC-1000-E radios, gigabit wireless Ethernet links may be established over distances of up to 3.4 miles with carrier or enterprise class availability, depending upon average weather conditions. Secure remote monitoring and control via SNMP are easily imposed by connecting to a LAN jack anywhere in the network. Its fiber-class data rate, superb quality of service, ease of installation and affordable cost make the PPC-1000-E an ideal solution for WiFi or mobile network extension and backhaul links, business WAN or IP telephony gateway connections, metropolitan area networks and rapid-deployment emergency communications.
John Stover tells DailyWireless:
“We see a lot of potential for E-band point to point links as quick and efficient high capacity data pipelines. The industry’s primary marketing focus has been on urban business areas or business campuses, but there are also a lot of suburban population centers that are beyond the reach of wired DSL. Even most SOHO businesses would be satisfied with a 348k connection, and one wireless gig-E link could extend 348k synchronous DSL connections to about 3,500 subscribers for more than 3 miles beyond the distance limit of existing wired DSL lines.
Gilland Electronics was established in the San Jose CA area in 1990, and has been importing and distributing ELVA-1 millimeter wave products in the Americas since 1997.
The “E” band may have advantages over the unlicensed 60 GHz band. That’s because, at 60 GHz, limited range was a feature. Oxygen molecules limit range right around 60 GHz. This was seen as an advantage for space-to-space communications – it couldn’t penetrate the atmosphere. Recent developments in CMOS may bring 60 GHz wireless HDTV connections home at gigabit rates.
But 60 GHz range is short. The “E” band, at 71-76/81-86 GHz, does not suffer from the extreme oxygen attunuation, using a notch in O2 attenuation and therefore gaining range benefits.
Other companies with gigabit wireless solutions include:
- GigaBeam with a point-to-point wireless solution called WiFiber. Google uses their point-to-point gear in their 71-76 GHz and 81-86 GHz radios to backhaul aggregatted hotspots. The current speed achieved by GigaBeam’s WiFiber is one Gigabit-per-second with future products capable of using the 10 Gigabit Ethernet protocol standard.
- Loea Communications has been operating a series of demonstration sites in the 71-76 GHz band over the past two years, including a 2.7 mile gigabit data link to move raw HDTV footage at the 2003 Super Bowl.
- Dragonwave offers microwave backhaul using licensed frequencies at 11, 13, 15, 18, 23, 24, 26, 28, and 38 GHz; as well as 24 GHz (unlicensed). Dragonwave is used by Earthlink and MetroFi for backhaul. DragonWave this week announced the signing of a strategic partnership agreement with Cedicom of Russia, a leader in the telecommunication market in Russia and the CIS countries.
